| To Mr. Clark. from EH. EH4/LG28.12.17. 28th Dec. 1917. WATER PUMP CASINGS COPAL VARNISHED X.3152 We recommend that the water pump casings should be treated in the same way as we treat the aluminium induction pipes. that is, with a coating of copal varnish then stoved. We consider this is much better than the "Ripolin" enamel used at present which peels off. EH. | ||
